Police are seeking tips in a city where several women of color have gone missing this year.

Another black teenage girl has gone missing in Chicago. According to WGN, 16-year-old Caniya Johnson was last seen on August 23 in the Englewood neighborhood on the city’s South Side.

Caniya is described as being five feet tall, weighing 135 pounds, with brown eyes, black hair, and a medium-brown complexion. NBC Chicago reported that she was last seen wearing blue jeans, a blue and gold Simeon Career Academy shirt that read “23,” and black and gold foam shoes.

This news comes two months after 14-year-old Aziya Roberts organized and led a march of about 150 people to bring awareness to the multiple black girls and women who have gone missing in Chicago — all of whom received inadequate media attention in the eyes of the activists. Prior to organizing the #WeWalkforHer march in June, Aziya had noticed that, since March, at least six girls and women had been reported missing on the city’s west side, prompting fears of a serial predator.

Four of the missing women have been found alive or are believed to be safe; two others, 15-year-old Sadaria Davis and 26-year-old Shantieya Smith, were found dead, and Chicago police have said there are no connections between the disappearances.

“I wanted to step up and take more responsibility and bring more awareness to the problem,” Aziya told Teen Vogue about her decision to organize for the missing women. “If it could happen to me, I need to start speaking up.”

In 2017, there were 219,484 black people reported missing in the United States, according to the National Crime Information Center — and black juveniles under 18 years old accounted for at least 77.1% of those missing people identified as black; when the age range expands to those missing under age 21, that number jumps to 82.2%.

Despite this being the case, missing black people don’t receive as much media coverage as missing white people — such as the recent case of Mollie Tibbets that prompted nationwide coverage by numerous media outlets. Vox reported that sociologist Zach Sommers found, in a 2016 study, that missing white women received a disproportionate amount of news coverage compared to women of color and men. According to NPR, white women are only about a third of the population, but accounted for half of the articles found for the study.

NBC Chicago reported that anyone with information on the possible whereabouts of Caniya Johnson should call Area South detectives at (312) 747-8274.
